Added support of Oracle

[avelis]

@pikhovkin I appreciate the effort to add Oracle support for django-silk. I see 2 PR's open. Is there a reason for that? Should those be discarded and this one be the only one for consideration to merge in?

You can remove 2 others PR's.

It seems the tests are failing. Can you fix them?

Also, does travis support oracle as a DB? If it does, it would be nice to add to .travis.yml to ensure compatibility.

We must get rid of the UUID fields, because django Oracle backend interprets them in SQL as a number, because of this an error occurs.
So I added the migrations in which I deleted these fields.
But tests check these UUID fields and raise error.

@albertyw I have not worked yet with travis or other like system.

@pikhovkin This PR needs a rebase to the latest django-silk:master, can you work this?
